Patent GB-125191-A (GB)
IPC: F16D65/06
Abstract: 125,191. Curtis, J. N., and Sampson, E. D. March 12, 1918. Compensating for wear.-Relates to mechanism of the kind described in Specification 29600/10 for automatically taking up slack due to wear of the brake blocks of railway vehicle brakes, and comprising a pair of toothed cams a, b of which one a is pivoted upon the end e of the brake arm x and engages a pin f on the pull-rod g and the other cam b is pivoted upon a pin d fixed to the pull-rod g, and engages a pin h on the brake arm x. According to one feature of the invention, the pin h is carried by a link c connected to the arm x and slides in a slot in the forked end of the rod g. When the lever w is raised to apply the brakes the pull-rod is moved by the cam a engaging the pin f and by reason of the differential movement of the pin h with respect to the pullrod, the pin h takes up a tooth of the cam b if the movement of the pull-rod is excessive and as the brakes are released, the cam a also drops the extent of a tooth thereby shortening the effective length of the pull-rod. In the event of sluggish release movement of the mechanism, a pin l on a pair of links k connected to the pin e comes into contact with teeth n on the cam band so pushes the rod g. The pin l also prevents any substantial movement of the rod g except by actuation of the lever w. Any tendency of the cam b to remain in a position in which the pin h is on the crest of a tooth is prevented by the engagement during the release movement of the links k with an arm or wedge i fixed on the pin h whereby this pin is given a partial rotation sufficient to move the cam slightly about its pivot d.

Title: Improvements in or relating to the simultaneous transmission of telegraphic and telephonic messages over the same line
IPC: H04M11/06
Filed: 1926-05-17
Abstract: 252,205. Siemens & Halske Akt.-Ges. May 18, 1925, [Convention date]. Eliminating effects or disturbing currents.-In a system of simultaneous telegraphy and telephony in which the telephone and telegraph transmitting circuits are associated with a common line through filter circuits, interference effects due to unequal earth capacities are eliminated by arranging the telegraph circuit so that these capacities act symmetrically on both sides of the filter circuit. In one arrangement, Fig. 2, an additional condenser 19 arranged on the opposite side of the Morse key 1 balances the earth capacities due to the battery 2. In another arrangement, earthed condensers are connected to both line wires at points between the filter coils 5, 6; 7, 8, respectively, the relative values of these condensers being adjusted until interference in the telephone circuit is a minimum. In a further arrangement, the battery 3 is divided, one half being arranged on each side of the key 1. In the arrangement shown in Fig. 4, the transmitting circuit is associated with the filter circuit 5 - - 9 through a transformer, which may have an earthed screen 24 to prevent capacitative effects. Fig. 6 shows an arrangement in which signals are transmitted by means of a condenser 30, which is charged from the battery 1 and then by simultaneously thrown keys is discharged through the filter-circuit and line. The double arrangement of condensers 30, 31 provides for signals of opposite polarity.

Abstract: 1,219,837. Radiographic apparatus. D. E. STOLLE. 15 March, 1968 [15 March, 1967], No. 12685/68. Heading H5R. An instrument (see Fig. 5) for examining pipe walls comprises a support means, e.g. cassette frame 10, to support a radiation sensitive film in a planar configuration, an extension means, e.g. bar 14, attached to said support means and fixedly positionable in alternative predetermined angular relationships with the support means, a penetrating radiation emitting source, e.g. 52, slidably attached to the extension means, and an adjustable flexible strap 30 attached to the extension means whereby the pipe 26 is held firmly against the extension means and tangential to the support means, there being means, e.g. corresponding calibrations, on the strap (Fig. 3, not shown) and on the bar 14, responsive to the outer circumference of the pipe to indicate the predetermined optimum position of the source along the extension means, and means to indicate the angle of incidence at which the radiation strikes the film. Preferably these last means are such that they indicate the point at which the radiation emitted by the source strikes the film at a right angle. A radiation impenetrable marker means 70 (Fig. 5) responsive to the position of the radiation source on the bar 14 may be positioned between the pipe and the film, as may be a radiation impenetrable calibration means, the calibration 92, of which is correlated with the calibration on the strap 30 and is adapted to interact with the marker means 70 to confirm the positioning of the source and indicate any variance of an image of the marker means on the film from its predetermined position, whereby the angle at which the emitted radiation beam strikes the film is indicated. Preferably the frame 10 is pivotally attached to the bar 14, the bar being pivotally attached to a support plate 12 rigidly attached to frame 10, plate 12 containing means, e.g. holes 18, 20, co-operating with pin 22, by which the alternate predetermined angular positions of the bar 14 may be established. The bar 14 is preferably attached to the pipe by a positioning bar 28, slidably connected to the extension bar so that this bar may be moved relative to the pipe to position the film support means 10 adjacent the pipe. Preferably the positioning bar 28 includes a pivoting lever 42 by means of which the strap 30 is tightened. The source 52 may be a radioactive source and is then appropriately shielded and collimated.

Abstract: 639,262. Fluid-pressure servomotor-control systems. ROLLS-ROYCE, Ltd. May 12, 1947, No. 12822. [Class 135] [Also in Group XXVI] In a fuel system for a gas-turbine engine in which an engine-driven pump 17 passes liquid through restricting means variable by speedselecting device 28 and in which means, e.g. a piston 12, responsive to the pressure drop across the restriction, is operative to vary the fuel delivery to the engine, the variable restricting means comprises the combination of a resiliently loaded valve 32 and a variable orifice 26 hydraulically in series, and variation of the effective area of the orifice is accompanied by a simultaneous variation in the resilient loading of the valve. Movement of the piston 12 varies the swash-plate of a multicylinder engine-driven pump 10 supplying fuel to injection devices 16. The output pressure of pump 17 is applied directly to piston 12, and the restriction means 26, 32 constitutes a leak on that fluid circuit. The means to vary restriction 26 comprises a valve 27 shaped so that the run-up of the engine at any point in the speed range is modified as desired. The pressure drop across valve 32 will not be affected by the flow therethrough as in the case of restriction 26. Specification 639,260 is referred to.

IPC: H03K3/286
Filed: 1966-03-25
Abstract: 1,113,306. Transistor bi-stable circuits. STANDARD TELEPHONES & CABLES Ltd. 25 March, 1966, No. 13284/66. Heading H3T. When a bi-stable circuit comprising a complementary pair of transistors T1, T2 is used to feed pulses to a line, a choke L1 partially isolates the circuit from the linewhile the circuit is being switched between states. As described, transistors T1, T2 are normally non-conductive until a negative pulse is received at one of the inputs 1-n when both transistors become conductive. After a short delay due to build-up of current in choke L1, a pulse is initiated in the twisted-pair output line. The pulse is terminated by a positive pulse fed to diode D2 or a negative-going pulse (from + 6 v. to -6 v.) fed to diode D3. Diode D5 isolates the load from the bi-stable circuit during the turn-off period; diode D4 prevents current via D5 to the base of T1 during the off state whilst diodes D6, D7, D8 limit the rise in voltage at their respective connections.
